SCA: security update for lti-consumer-xblock (GHSA-7j9p-67mm-5g87)

low Tenable Self-Hosted Container Security Plugin ID 434189

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LTI Consumer XBlock implements the consumer side of the LTI specification enabling integration of third-
 party LTI provider tools. Versions 7.0.0 and above, prior to 7.2.2, are vulnerable to Missing
 Authorization. Any LTI tool that is integrated with on the Open edX platform can post a grade back for any
 LTI XBlock so long as it knows or can guess the block location for that XBlock. An LTI tool submits scores
 to the edX platform for line items. The code that uploads that score to the LMS grade tables determines
 which XBlock to upload the grades for by reading the resource_link_id field of the associated line item.
 The LTI tool may submit any value for the resource_link_id field, allowing a malicious LTI tool to submit
 scores for any LTI XBlock on the platform. The impact is a loss of integrity for LTI XBlock grades. This
 issue is patched in 7.2.2. No workarounds exist. (CVE-2023-23611)
